Pre-Compliance EMC Testing-Worth the Time!
Pre-Compliance EMC Testing-Worth the Time! Developing a new product? Build EMC into your device by testing it regularly during the development process. Pre-Compliance EMC Testing during development helps you locate and correct EMC issues at home in your facility. This spares you the time and expense of testing at a registered compliance lab. An RF Shielded EMC Enclosure provides the low ambient RF level necessary to test your product for emissions, susceptibility, and immunity. The equipment required to do your...

Nothing is “simple” anymore-needs Change!
Nothing is "simple" anymore-needs Change! When I first came to VTT, our manufacturing product line was fairly simple. RF Shielded Enclosures, RF Shielding Curtains, RF Shielding Garments were about it! Today, we find that our customers are always finding new and different needs for our conductive textile products. An RF Shielded enclosure has become a "suite" of rooms with more isolation than ever. Requests for Foyers, removable walls, are routine requests rather than unusual. RF Shielding Curtains are now "arrays...

RF Shielded EMC Testing Enclosures-Size Matters!
RF Shielded EMC Testing Enclosures-Size Matters! Electronic devices come in all sizes. All of the devices require EMC Compliance Testing in order to be marketed. This testing determines whether the device can work effectively in a shared electromagnetic environment. All devices emit RFI radiation and electromagnetic fields. These emissions can adversely affect the function of the other devices. The problem boils down to two terms, emissions or susceptibility. The RF emissions of an electronic device must meet certain applicable standards. ...

Conductive Textiles help make Travelling Safe!
Conductive Textiles help make Travelling Safe! Planes, trains, and automobiles depend on conductive textiles in many ways. They keep the driver or pilot aware of the engagement of safety restraints by the passengers before beginning the trip. If you drive automobiles, you are well aware that there are sensors present in the steering wheel that determine if the driver is in proper position and paying attention to his surroundings. If the car wanders in its lane, sensors notice this and...

EMC Compliance Testing-what’s the Point?
EMC Compliance Testing-what's the Point? Every electronic device must pass EMC Compliance Testing to make it to the market! The reason for this requirement is to lessen the amount of RFI/ EMI in our environment. More importantly, it is to lessen the RFI and EMI in our environment that adversely affects the function of other devices present in the shared electromagnetic environment. All electronic devices emit RFI/EMI. In general, electromagnetic interference doesn't cause a decrease in function of the devices...

RF Shielded Enclosures-Testing at Home!
RF Shielded Enclosures-testing at Home! Preparing for Final Compliance EMC Testing is difficult. One of the best ways to prepare for this test is to prepare your product during development. Testing your product in your home environment during development builds EMC into your device from the start and is the best way to proceed. Pre-Compliance EMC Testing can be done easily at your development site. It actually saves time in development, by intercepting EMC issues along the way rather than...

Large RF Shielded Enclosures-Giants!
Large RF Shielded Enclosures-Giants! I always say that VTT fabricates RF Shielded Enclosures to satisfy the needs of our customers, whether it's as small as our 3D Pouch, our "small test lab", or a much larger one. This year, we are receiving orders for "Testing Megastructures", very large testing enclosures. RF Shielded enclosures provide the low ambient RF environment required for Pre-Compliance EMC testing. The size of the testing enclosure is typically dependent on the size of the Device Under...

Testing Times demand logical Preparation!
Testing Times demand logical Preparation! So many things in our lives depend on test results! In my case, my Dental License depended on my Dental Board Exam results, passing is necessary to license! In the world of electronic devices, passing Final EMC Compliance Testing is necessary to market the device. Logical preparation dictates testing your device often during development in preparation for the "big day"! You know the EMC standards that your device must meet. Pre-Compliance EMC Testing in your...
